Control
3. 8-bit conversion mode (while M8161 is ON)
(M8161 is used also for the RS, ASCI, CCD and CRC instructions.)
Each ASCII code stored in the low-order 8 bits of each device
and later is converted into a hexadecimal code,
and transferred to device
and later in 4-digits units. The number of characters to be converted is specified by
"n".
M8161 is also used for the RS, ASCI, CCD and CRC instructions. When using the 8-bit mode, set M8161 to normally
ON. M8161 is cleared when the PLC mode is changed from RUN to STOP.
